Watch Jeopardy with 2 or more people. Whoever screams out the correct answer first, the others must take a shot of beer. You can't guess again until you have taken your shot AND poured yourself another. This way, if someone gets on a roll, you can really fuck someone up.

Final Jeopardy: write down a bet (in beer shots) after finding out the category. Write down your answer during the alotted time. If you are right, but someone is also right and wagered more than you, you must drink the difference. If you are wrong, you must drink the sum of your wager and the wagers of all those who got it right. If you play with a lot of people and this happens, one might have to drink between 25-50 shots, which is pretty damn hard and takes forever.
